Greece's public order minister says the coalition government has made superhuman efforts to comply with the Eurozone's austerity demands to secure a economic bailout.
Christos Papoutsis says the country's social and economic system is stretched to its limits.
He was speaking after the cancellation of a meeting of Eurozone finance ministers on the bailout, which Greece needs to avoid defaulting on its debts next month.
Eurozone ministers, who had demanded Greece find an extra €325m of savings, had been set to meet in Brussels.
Current Eurozone president Jean-Claude Juncker said the talks would be replaced by a conference call
Mr Juncker says the Greek coalition has not shown how it will make the extra cuts they are demanding, nor has it given a cast-iron commitment to stick to them.
Greece urgently needs €130 billion to avoid defaulting on its debts in March.
